The detent projection sequence with toothed surface is played, such structure can guarantee that the actual (real) thickness between toothed surface and the profiling flank of tooth obtains
To ensure, during powder metallurgy, the suppressible density of the powder of toothed surface position is higher, to directly promote tooth form
The working strength and hardness in face.
2, the utility model is angular wheel, and the detent projection of the toothed surface and the detent projection of the profiling flank of tooth are equal
It continuously gets higher from outer to inner, actually the profiling flank of tooth is the face of gear to misplace, the detent projection of the profiling flank of tooth and the tooth of toothed surface
The basic reason of the setting of shape projecting parallel, the setting profiling flank of tooth is: during powder metallurgy, avoiding face of gear and profiling
Uneven thickness between the flank of tooth guarantees the powder density of toothed surface position, ensures the working strength and hardness of toothed surface.
3, gear body described in the utility model is inwardly recessed to form a concave portion in the middle part of toothed surface one end, and recessed portion both may be used
The problem of to go de-stress to concentrate, and raw material are saved, at least two shrinkage pools are provided in recessed portion, preferably three are recessed
Hole, shrinkage pool is in actual use, carrying out gear body described in emergency stop, guaranteeing the stability of structure.
4, it is provided with axis hole in the middle part of the gear body of the utility model, it can be according to the requirement of actual use in axis hole
Keyway is added, which is used for external ROTATING SOURCE, and gear body is provided with extended segment in profiling flank of tooth one end, the extended segment
For promoting the intensity of gear body, the utility model carries out the thickness of toothed surface position to promote the intensity of toothed surface
It limits, therefore corresponding can also be reduced with the link position of external ROTATING SOURCE, therefore compensated by the extended segment of one, protected
Demonstrate,prove the stability of structure.
